Jenna Fischer Reveals the Secret to Her The Office Chemistry With John Krasinski

There is a secret to Jenna Fischer and John Krasinki's chemistry on The Office and it will make you say, "Awww!" You see, a little part of the two actors were just like Pam and Jim, Fischer explained to Andy Cohen on Watch What Happens Live.

"John and I have real chemistry," Fischer said after a caller asked how close they were or if it was just good acting. "There's like a real part of me that is Pam and a real part of him that's Jim and those parts of us were genuinely in love with one another. But in real life we aren't totally Pam and totally Jim, so in real life we're not the perfect match…he was like a type of spouse that I had for a long time, he was my partner and we will always be close because of it."

Fischer and Krasinski starred in The Office for nine seasons on NBC. Viewers watched as Fischer's Pam went from the engaged receptionist Jim had an unrequited crush on to the married couple viewers so desperately said "Relationship goals!" about.

Now Fischer is starring in NBC's You, Me and the Apocalypse alongside Rob Lowe and Megan Mullally and Krasinski is super buff and on the big screen (with Daivd Denman, the guy who played Pam's ex-fiance Roy on The Office) in 13 Hours.

Watch What Happens Live airs Sunday-Thursday at 11 p.m. on Bravo. You, Me and the Apocalypse premieres Thursday, Jan. 28 at 8 p.m. on NBC.
